HIV is a sexually transmitted disease. For any risk, you have to insert your penis inside of a vagina or an anus with out condom.
You inserted your middle finger which is not penis, they both are different parts of the body. Therefore, there was no risk for HIV transmission.
Also, kissing and other form of casual contact is not a risk for HIV transmission.
You didn't posses any risk, your symptoms were not specific to HIV. You didn't need to test. PEP was not necessary.
If you used condom and it didn't break, there was never a risk of HIV. Kissing and fingering are not risks. If they were, we would see literally millions of new cases every single day.
The only ways HIV is spread are:
-Sharing needles to inject drugs.
-Unprotected anal/vaginal penetrations.
-Mother to child.
I don't understand why they gave you PEP, as it should be used only in those cases of realistic risk. PEP can be really toxic !!
But even if you had had a risk, symptoms are never used to diagnose HIV, as they can be confusing and different depending on the person. But for sure, they never show up right the day after the risk. They can take up to several weeks, and actually sometimes, there are no symptoms at all.
All the best.
